add centerZero feature

[Ludovic]

Hello,
As the “includeZero”, could it be possible to add the “centerZero” option to set min = – max value for at least axisY types in the Axis.prototype.calculateAxisParameters function?
The code just after applying includeZero (//Apply includeZero) could be something like :

if (this.centerZero) {
    // Force includeZero
    if (max < 0)
        max = 0;
    if (min > 0)
        min = 0;
    // Apply centerZero
    if (max > -min)
        min = -max;
    else 
        max = -min;
}

This would be much easier to do it that way instead of to update the axes min/max after rendering, and more after zooming.

Thank you

Thanks for the suggestion. I will discuss this behavior with the team for future releases.
